Gas-fired air handling unit shipped to paper maker in Peru
A
gas-fired air handling unit has been supplied by Mark Climate Technology
to a paper maker in Peru. The AHU 35-25 unit provides 32,000 cubic metres per hour of air and is equipped with two G+200 heating modules. Modulating recirculation dampers provide the option to recirculate air from the building and therefor lower the overall gas consumption of the unit. As standard, the Mark AHU series is made from seawater- resistant aluminium panels. With the stainless-steel heat exchangers of the Mark G+ condensing heating modules, this provides an excellent solution for the humid and coastal environment of Lima, the capital of Peru. The unit was divided in four sections for shipping in a standard 40ft container. On site in Peru, the AHU was assembled by the client’s local service
team. Fine commissioning of the control system was carried out from Mark’s headquarters in the Netherlands, using integrated webserver technology. The AHU is used for heating a
new warehouse to a temperature of 35 deg C. This temperature is required for post-drying of manufactured paper products. A second unit has recently been ordered.

Improvements to wastewater treatment processes
Valmet and Kemira have agreed to develop wastewater and sludge treatment applications for industrial plants in Europe, including paper mills. Reliable real-time measurement data will increase the water treatment process visibility and enable predictive and proactive process management. The target is to bring significant savings and efficiency improvements to customers.
The partnership combines
Valmet’s comprehensive analyser and measurement technology, process optimisation know-how and on-site service network with Kemira’s strong chemistry and process optimisation expertise in municipal and industrial water treatment. The agreement widens the existing industrial internet ecosystem collaboration between the two companies. “Polymers and chemicals
are an important part of the wastewater treatment process which is one reason why this collaboration with Kemira is a great opportunity for us,” says Heli Karaila, manager for wastewater automation at Valmet. “Especially in sludge dewatering, the right chemicals selection is one of the key elements to achieve the best performance.”
Jussi Ruotsalainen, application development manager at
Kemira, added: “We are actively expanding our portfolio of smart chemistry through the KemConnect platform, for example sludge dewatering and phosphorus treatment. As part of this full-service approach, it makes perfect sense to partner up with a leading industrial automation hardware, software and equipment service provider like Valmet.” More information from www.
